Mathematical operations were carried

Due to the war and the plague Schickards work describing the mechanism of the adding machine disappeared and was found only in the th century. Pascalina is based on the tens transfer mechanism known to us similar to that found in the Schickard adding machine. However if Chiccard added the then innovative Napere Sticks to the adding machine to facilitate multiplication and division Pascalina only has an adder.

Out in the decimal system using wheels connected to each other by gears. Each wheel had numbers from to . When turning after the next wheel in ascending order turned one forward. Thus tens hundreds thousands and so on were recruited. It was impossible to turn the wheel back. Later versions Buy Email List of Pascalina made it possible to add up to . In the version of Pascaline shown in the photo below at the top of the adding machine there are windows on which numbers and the final number are displayed. At the bottom there are wheels for dialing numbers.



They had to be dialed from left to right just like in old telephones select the window corresponding to a particular number and scroll it clockwise until it stops at the bottom of the wheel. When adding the second addend is entered from left to right the arrangement of numbers is the same as when adding in a column. To reset the readings you must first set all the wheels to so that all windows have and then turn the outer right wheel to.
